Abstract
Description
technical field
[0001] The invention relates to a production process and equipment in the tobacco industry, in particular to a method and device for controlling the oxygen content in the drying process of drum shredded tobacco in the tobacco processing process. Background technique
[0002] Cut tobacco drying process is one of the key processes in the production process of cigarette shreds. In this process, the shredded tobacco is heated and loses moisture at the same time through the conduction heat transfer of the tube wall and the convective heat transfer of hot air, so as to realize the purpose of loosening and curling the shredded tobacco and increasing the filling capacity of the shredded tobacco; The chemical reaction improves the taste and smoking quality of shredded tobacco. The drum device has the advantages of large processing capacity, flexible operation, and relatively low cost, and has become the main method for drying materials in the tobacco shred process. ...
